ADDING OIL: INITIAL USE
NOTE: This unit was shipped without oil in the crankcase. Oil must
be added before starting the unit.
NOTE: This unit comes with a 3.04 fluid oz. (90 ml) container of oil.
1. Set the unit on a flat, level surface.
2. Unscrew the oil fill plug (Fig. 6).
3. Pour the entire container of oil into the oil fill hole (Fig. 6). DO
NOT overfill. Refer to Checking the Oil Level.
NOTE: Never add oi
l t
o the fuel tank. This unit has a four-stroke
engine. DO NOT mix oil with gasoline.
4. Wipe up any oil that may have spilled.
5. Reinstall the oil fill plug.
NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 6).
WARNING:
OVERFILLING THE CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY. Check the oil level
before each use. The importance of maintaining the proper
oil level cannot be overemphasized. Change the oil
according to the Maintenance Schedule.
USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance
problems. Use only fresh, clean unleaded gasoline.
NOTE: This unit has a four-stroke engine. DO NOT mix oil with
gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can ma
ke
fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
If using a blended fuel:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL
®
or an equivalent
Using Fuel Additives
Use a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent, to inhibit corro
sion and minimize gum deposits. Add 0.8
oz. (23 ml) of fuel additive per gallon of fuel, according to the
instructions on the container. NEVER add fuel additives directly to
the unit's fuel tank.
CAUTION:
DO NOT USE E85 FUEL IN THIS UNIT.
It has been proven that fuel containing greater than 10%
ethanol will likely damage this engine and void the warranty.
USING THE RIGHT OIL
Use a high-quality SAE 30 weight oil. DO NOT use dirty oil. Failure
to use clean oil of the correct type can cause premature engine
wear and failure.

FUELING THE UNIT
1. Position the unit with the fuel cap facing up.
2. Slowly remove the fuel cap.
3. Place the fuel container spout into the fuel tank fill hole and fill
the tank.
NOTE: Do not overfill the tank.
4. Wipe up any fuel that may have spilled.
5. Reinstall the fuel cap.
6. Move the unit at least 30 ft. (9.1 m) from the fuel container and
the fueling site before starting the engine.
WARNING:
Gasoline is extremely flammable. Ignited
vapors may explode. Always stop the engine and allow it
to cool before filling the fuel tank. Do not smoke while
filling the tank. Keep sparks and open flames at a distance
from the area.
WARNING:
Remove the fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the fuel cap
securely in place.
WARNING:
Add fuel in a clean, well-ventilated outdoor
area. Wipe up any spilled fuel immediately. Avoid creating
a source of ignition for spilled fuel. Do not start the engine
until fuel vapors dissipate.

OPERATION
ADJUSTING THE CUTTING DEPTH
1. Gently pull the depth adjustment lever away from the wheel
bracket (Fig. 12).
• To increase the cutting depth, lower the edger blade. Move the
lever toward the rear of the wheel bracket.
• To decrease the cutting depth, raise the edger blade. Move
the lever toward the front of the wheel bracket.
HOLDING THE UNIT
• Stand in the operating position (Fig. 11). Stand up straight. Do
not bend over.
• Keep feet apart and firmly planted.
• Hold the handle firmly with both hands.
WARNING:
Always wear eye, hearing, hand, foot and
body protection to reduce the risk of injury when operating
this unit.
TIPS FOR BEST RESULTS
• After starting the engine, keep the unit tilted back so the blade
does not touch the ground. Move the unit to the desired location
and slowly lower the blade into the ground.
• DO NOT force the unit. Make the first cut no more than 1/2”
deep. Increase the depth by 1/2” and cut the area again. Repeat
this process until the desired depth is achieved. Refer to
Adjusting the Cutting Dept
h.
• C
ut at a slow, even pace.
• Frequently check the condition of the blade. As it wears, the
blade will become smaller, reducing the cutting depth. Replace
the blade as needed. Refer to Replacing the Edger Blade.

CHECKING THE OIL LEVEL
1. Stop the engine and allow it to cool.
2. Set the unit on a flat, level surface.
NOTE: Failure to keep the engine level may result in oil overfill.
3. Clean the area around the oil fill plug (Fig. 15) to prevent debris
from entering the oil fill hole.
4. Unscrew the oil fill plug.
5. Look into the oil fill hole; use a flashlight if necessary. The oil
level should just touch the b
ot
tom thread of the oil fill hole
(Fig. 16).
• If the oil level is too low, slowly add oil to the oil fill hole until
the oil is at the correct level.
• If the oil level is too high, tip the unit and drain the excess oil
into an appropriate container.
6. Wipe up any oil that may have spilled.
7. Make sure the O-ring is in place on the oil fill plug (Fig. 15).
8. Reinstall the oil fill plug.
WARNING:
Check the oil level before each use. The
importance of maintaining the proper oil level cannot be
overemphasized.
WARNING:
DO NOT overfill the crankcase.
OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS
PERSONAL INJURY.
CHANGING THE OIL
Change the oil while the engine is still warm. The oil will flow freely
and carry away more impurities.
1. Clean the area around the oil fill plug (Fig. 15) to prevent debris
from entering the oil fill hole.
2. Unscrew the oil fill plug.
3. Tip the unit vertically to pour the oil out of the oil fill hole and into
a container (Fig. 17). Allow ample time for complete drainage.
NOTE: Dispose of
the
old oil according to federal, state and local
regulations.
4. Wipe up any oil that may have spilled.
5. Pour 3.04 fl.oz. (90 ml) of SAE 30 oil into the oil fill hole.
NOTE: DO NOT overfill. Refer to Checking the Oil Level.
6. Wipe up any oil that may have spilled.
7. Make sure the O-ring is in place on the oil fill plug (Fig. 15).
8. Reinstall the oil fill plug.

MAINTAINING THE AIR FILTER
Failure to maintain the air filter can result in poor performance or can
cause permanent damage to the engine. Engine failure due to
improper air filter maintenance is not covered by the product warranty.
Cleaning the Air Filter
1. Open the air filter cover: unscrew the cover screw and swing the
air filter cover to the right (Fig. 18).
2. Remove the air filter (Fig. 19).
3. Wash
the
air filter in detergent and water. Rinse the air filter
thoroughly and allow it to dry.
4. Lightly coat the air filter with clean SAE 30 oil.
5. Squeeze the air filter to spread and remove excess oil.
6. Reinstall the air filter (Fig. 19).
NOTE: Operating the unit without the air filter and air filter cover will
VOID the warranty.
7. Close the air filter cover: insert the hooks on the air filter cover
int
o t
he slots on the backplate. Swing the air filter cover to the

ADJUSTING THE IDLE SPEED
If the engine will not idle properly:
1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.
• If the engine stops, increase the idle speed. Use a small
Phillips screwdriver to turn the idle speed screw clockwise,
1/8 of a turn at a time, until the engine idles smoothly (Fig. 20).
• If the blade spins when the engine idles, reduc
e t
he idle
speed. Turn the idle speed screw counterclockwise, 1/8 of a
turn at a time, until the blade stops moving (Fig. 20).

se.
5. Inspect the spark plug. If the spark plug is cracked, fouled or
dirty, replace it with replacement part #794-00098, a Champion
QDZ4H or an equivalent spark plug.
6. Use a feeler gauge to set the air gap at 0.025 in. (0.635 mm)
(Fig. 22).
7. Install the spark plug in the cylinder head. Tighten the spark plug
with a 5/8-inch socket, turning it clockwise until snug.

Clean the blade with a household cleaner to remove gum buildup.
Wipe the blade with a light machine oil to prevent rust.
WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit.
STORAGE
• Never store a fueled unit where fumes may reach an open flame
or spark.

3. Allow the engine to cool. Remove the spark plug and put 5
drops of any high-quality motor oil into the cylinder. Pull the
starter rope slowly to distribute the oil. Reinstall the spark plug.
4. Thoroughly clean the unit an
d i
nspect it for any loose or
damaged parts. Repair or replace damaged parts and tighten
loose screws, nuts or bolts.
